Contactless face recognition access control system

In the epidemic environment, people don't want to touch things outside, so we create a face recognition access control system that does not require contact. When it is detected that a person is approaching the door, the face recognition device is awakened to save power consumption. When the face recognition passes, the door is controlled to open.

NanoClon 0.01: used to assemble mClon type robots

This circuit has everything you need to assemble a mClon-style robot, without the need to find the missing Arduino circuit from RobotDyn used in the ShieldClon version.

Components can be SMD or THT, except the boost circuit/lithium battery charge controller is SMD, the 1206 and 0805 components are larger than the usual 0603 and 0402). You can choose not to solder the boost smd component and just solder the Bat-Vcc selector on the bottom to use the power bank.

posture correction robot

It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem.
